Which of the following has the highest value for bond order - C 6 H 6 , C O 3 2 - , N O - and SO 4 2 − ?

Step-by-step solution

Bond order (BO) can be calculated using the following methods: (i) B O = T o t a l n u m b e r o f b o n d s a s s o c i a t e d w i t h t h e c e n t r a l a t o m N u m b e r o f σ b o n d s a s s o c i a t e d w i t h t h e c e n t r a l a t o m (or) B O = T o t a l n u m b e r o f b o n d s b e t w e e n t w o a t o m s T o t a l n u m b e r o f r e s o n a n c e s t r u c t u r e s (ii) B O = N u m b e r o f b o n d i n g e l e c t r o n s - N u m b e r o f a n t i b o n d i n g e l e c t r o n s 2 We use both
